IMPROVEMENT lN HARVESTERS.

Specification forming part of Letters Patent No. 28,061, dated May 1,1860.

To all whom Ait may concern.-

Be it known that I, S. T. BRUCE, of Marshall, Saline county, in theState of Missouri, have invented anew and useful Improvement inHemp-Harvesters; and I do hereby declare that the following is a fulland exact description thereof, reference being had to the accompanyingdrawings, and to the letters of reference marked thereon.

My invention relates to certain improvemen ts in hemp-harvesters; and itconsists in certain improvements in the delivering apparatus, as will behereinafter fully described.

To enable those skilled to make and use my invention, I will proceed todescribe its construction and operation,referring by letters to theaccompanying drawings, forming part of this specification, and in which-Figure l represents a perspective \iew of my improved machine. Fig. 2represents a top view of my Inachine,and Fig.3 represents a sideelevation ot' the same,similar letters denoting the same parts indili'erent views.

A represents the main frame ofthe machine, B, the drivingwheel; O, themain shaft.

E is the iinger-bar,on which is arranged the cutting apparatus in theusual manner. (Not shown in the drawings.)

F is the divider.

G and G' are the two guides, which extend from the front end of innerframe-piece, A, to a vertical post, g, as seen at Figs. l and 2, andform afender to sustain and support the hemp during the progress of themachine until the cutters come in contact with it.

H and I are two guards, extending from the forward end of the divider Fupward past a post, a, to which they are secured, and K its lower guard,ruiming on nearly same plane with H and I.

L is a polygonal tapered carrier-roll, which is supported in suitablebearings a short distance in the rear of the cutting apparatus, andwhich is rotated on its axis by a cord, b, passing from a pulley, D,over a pulley, a., on the roll.

M is an auxiliary carrier-roll,which is hung to turn freely on its axis.Said roll M is cylindrical, and is arranged obliquely to the roll andalso to the horizontal plane of roll L. The relative arrangement oftherolls L and M with each other and with the machine will be best comprehended b v reference to the drawings.

The guards Gr II and I K are so constructed and arranged as to form twofenders, both curving around toward the rear of the fratrie (see Fig. 2)to assist in the conveyance of the cut inaterialfrom the cuttingapparatusaround to the rear of the machine and out of its track in thereturnswath.

The roll L is made polygonal to more readily carry the cut materialbackward, and it is made tapering, so that the end near thedivider'board will carry the material (which at this side has farther totravel) more rapidly, it being larger' and consequent-ly having agreater velocity.

It will be understood that by the combination ofthe tapering roll L,rotated immediately back ot' the cutting apparatus with theobliquely-set carrier-roll M,in connection with the guiding-fendersformed on either side ot' the cutting apparatus, as described, the cntmaterial is effectually conveyed from the cutting apparatus round to theback ofthe fratrie of the machine and out of its track in cutting thenext swath.

Havingexplained rnyinvention,whatIclainI, and desire to secure byLetters Patent, is-

l`he combination ofthe polygonally-shaped tapering roll L, rotatingimmediately back ot' the cutting apparatus, with the obliquely-setcylindrical roll Ill and guards G G and H, I, and K, the whole arrangedand operating as specified, for the purpose set forth.

In testimony whereof I have hereunto set my hand and affixed my sealthis 24th day ot' October, 185).
